Rearranging jobs can be created when there are not enough target free spaces for containers coming out of a port back to the grid. If any of the above criteria are met, the central computer system searches for the best edge target cell, and the best source container/cell for the job.

Un procédé et un système de réagencement de contenants dans un système de stockage et de récupération automatisé comprend une structure de cadre (100) formant une structure de grille de stockage tridimensionnelle (104) destinée à stocker des contenants de stockage (106) pour le stockage d'articles, la structure de grille (104) formant des colonnes de stockage verticales (105) comprenant chacune une zone horizontale définie par la taille d'une ouverture d'accès (112) de la colonne de stockage verticales (105), et la structure de cadre comprenant un système de rails (108) disposé au-dessus des colonnes de stockage (105), le système de rails comprenant une pluralité de rails s'étendant dans une direction X et une direction Y pour former une grille, les rails définissant un périmètre de chaque ouverture d'accès (112) au-dessus de chaque colonne de stockage (105), le système de rails (108) fournissant des itinéraires disponibles dans la direction X ou la direction Y pour des véhicules de manipulation de contenants (201, 301) manipulant et transférant les contenants de stockage (106) vers et depuis les colonnes de stockage (105), le procédé comprenant les étapes consistant à : vérifier s'il y a suffisamment d'espaces libres le long d'au moins l'un des bords de la grille du système de stockage et de récupération, vérifier s'il y a suffisamment d'espaces libres dans les cellules non périphériques de la grille du système de stockage et de récupération pour effectuer des opérations normales, créer des tâches de réagencement dans le système informatique central s'il y a des espaces libres le long d'au moins l'un des bords de la grille du système de stockage et de récupération et s'il n'y a pas suffisamment d'espaces libres dans les cellules non périphériques de la grille du système de stockage et de récupération pour effectuer des opérations normales, informer des véhicules de manipulation de contenants en vue de la réalisation des tâches de réagencement et poursuivre la procédure normale sur la grille du système de stockage et de récupération après que les véhicules de manipulation de contenants ont effectué les tâches de réagencement.
